(Phys.org) —Reports given by experts in the space-health field suggest it might take longer for humans to build a colony on Mars than has been expected. Such experts speaking to attendees at the recent "Humans 2 Mars Summit" in Washington D.C. expressed concern about the dangers of Martian dust. They believe the health hazards posed by the Martian regolith could prevent humans from colonizing the planet anytime soon. http://phys.org/news287394874.html Space & Earth Fri, 10 May 2013 09:10:02 EST news287394874 A phenomenon first observed by an ancient Greek philosopher 2,300 years ago has become the basis for a new device designed to harvest the enormous amounts of energy wasted as heat each year to produce electricity. The first-of-its-kind "pyroelectric nanogenerator" is the topic of a report in ACS' journal Nano Letters. http://phys.org/news258813997.html Nanotechnology Wed, 13 Jun 2012 14:20:01 EST news258813997 Expedition 31 Flight Engineer Don Pettit of NASA has taught more than half a million internet viewers how microgravity affects scientific principles by using everyday objects on the International Space Station. In the latest video, Pettit takes his demonstrations to the next level by using sound to oscillate water placed on a speaker and letting the droplets fly. http://phys.org/news255594489.html Space & Earth Mon, 07 May 2012 07:30:27 EST news255594489 (PhysOrg.com) -- Bartosz Grzybowski, a physical chemist at Northwestern University, and his team of colleagues offer evidence in a paper published in Science, that shows that what scientists have believed to be true about the causes behind the creation of static electricity, is wrong. Instead of one object winding up with more or less electrons as a result of rubbing together, they claim, there is an actual transfer of slight amounts of actual material. http://phys.org/news228562191.html Physics Wed, 29 Jun 2011 10:31:00 EST news228562191 (PhysOrg.com) -- Scientists at the U.S. Department of Energy's Brookhaven National Laboratory have helped to uncover the nanoscale structure of a novel form of carbon, contributing to an explanation of why this new material acts like a super-absorbent sponge when it comes to soaking up electric charge. The material, which was recently created at The University of Texas - Austin, can be incorporated into "supercapacitor" energy-storage devices with remarkably high storage capacity while retaining other attractive attributes such as superfast energy release, quick recharge time, and a lifetime of at least 10,000 charge/discharge cycles. http://phys.org/news224426583.html Nanotechnology Thu, 12 May 2011 14:00:48 EST news224426583 (PhysOrg.com) -- Engineering researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. http://phys.org/news177672319.html Nanotechnology Tue, 17 Nov 2009 09:25:53 EST news177672319 (AP) -- NASA tried for hours Tuesday to launch its newest rocket for a shakedown flight, but clouds and high wind kept it stuck on the pad. http://phys.org/news175870090.html Space & Earth Tue, 27 Oct 2009 13:50:29 EST news175870090
